Setting out device

1. A setting out device for use with at least one tachymeter comprising: a rod which can be set vertically on a target point in the area surrounding a terrain point to be set out; a reflector which is arranged on the rod for tachymetric detection of the target point by the tachymeter; a transmitting and receiving device for exchanging information with the tachymeter; a computing circuit for determining deviations in position between the target point and terrain point; and an auxiliary setting out device for marking the position of the terrain point to be set out.

2. The setting out device according to claim 1 , wherein optical means are provided for marking the position of the terrain point to be set out.

3. The setting out device according to claim 2 , wherein the auxiliary setting out device comprises a laser device which is provided with a diffractive-optic element for generating a light pattern directed to the area surrounding the target point in the form of a grid, a point raster and/or concentric circles.

4. The setting out device according to claim 1 , wherein the auxiliary setting out device comprises a laser device for generating a punctiform mark which is directed to the surrounding area of the target point and which can be deflected in two coordinate directions over the surrounding area.

5. The setting out device according to claim 1 , wherein the auxiliary setting out device has a transmitting module arranged at the rod, near the ground, for sending position values, via modulated sound waves and/or electromagnetic waves, and a manually displaceable reception module for receiving the position values and for marking the terrain point to be set out.

6. The setting out device according to claim 5 , wherein the transmission of the position values is provided by ultrasound, the reception module has a reference point which can be made to coincide with the terrain point to be set out, and a device is provided for permanently marking the position of the terrain point after coinciding with the reference point.

7. The setting out device according to claim 6 , wherein the reception module has a color pointer for marking the terrain point to be set out in the terrain in color.

8. The setting out device according to claim 1 , wherein the transmitting and receiving unit is coupled to the rod in a detachable manner.

9. The setting out device according to claim 1 , wherein the transmitting and receiving device has a display for displaying information.

10. The setting out device according to claim 1 , wherein the transmitting and receiving unit has an operator's control for entering information.

11. The setting out device according to claim 1 , wherein the rod has a ground-side part and a part which can telescope vertically upward, the reflector being arranged at the telescoping part, and the telescoping part is guided in a defined position allocation relative to the ground-side part.

12. The setting out device according to claim 11 , wherein the transmitting and receiving unit can be fastened to the telescoping part, and means are provided for detecting the position correlation between the telescoping part and the ground-side part.

13. The setting out device according to claim 9 , wherein the display is constructed for displaying information about the coarse orientation of the rod in the area surrounding the terrain point to be set out.

14. The setting out device according to claim 13 , wherein direction orientation is carried out by a position signal which is displayed on the display and which can be turned on and off.

15. The setting out device according to claim 13 , wherein distance orientation is arranged at the display by a blinking light with variable blinking frequency, wherein different blinking frequencies signal too great a distance, a correct distance, and too little distance.
